Hot topics in monitoring solar irradiance

Feb 2019

We have a lot of contacts with existing and prospective customers in the solar energy industry; at exhibitions, in workshops or by email and through the Kipp & Zonen support system. Many of the same issues keep coming up, in one form or another. So, we have decided to put together a whitepaper that addresses the most common requests for information and explanation. This is particularly topical because there is a lot of confusion resulting from recent changes in key international standards.

Kipp & Zonen Pyranometers, is an 11 better than a 10? You decide.

Nov 2018

Historically, Kipp & Zonen pyranometers with a higher model number have better specifications and a lower measurement uncertainty. As a result, there has been some confusion in the market and the impression that the CMP10 and Smart SMP10 models are in some way inferior to their CMP11 and SMP11 cousins.

In fact this is not true. If you look at the brochure for our pyranometer range you will find that CMP10 and CMP11 share the same column in the CMP model range specification table, as do the SMP10 and SMP11 models in the SMP range table.

RT1 rooftop sensor exceeds expectations

Sep 2018

Last week my product management dashboard started blinking. But why? It turned out to be the alarm I’ve set almost a year ago for reaching 500 delivered and invoiced RT1 sensors. Time for a small celebration as the normal product adaptation period in our market is 3 to 4 years and the RT1 isn’t even a year old. Evidently the RT1 is the right product at the right time.

The Difference between Horizontal and Tilted Global Solar Irradiance

Dec 2013

Measuring solar irradiance in a highly accurate way is achieved by using a pyranometer complying with ISO 9060. Although most meteorological data is based on horizontally mounted pyranometers, with Photovoltaic (PV) panels it is also important to know the tilted global solar irradiance. This article explains more about measuring solar irradiance and the difference in horizontal and tilted pyranometers.
